Abstract

The surface tension of liquid Fe-O alloys was measured at temperatures ranging from 1621 K to 2006 K (1348 °C to 1733 °C) under a He-Ar atmosphere by using the oscillating drop method with an electromagnetic levitation facility. The experimental results were compared with the calculated ones based on the ideal adsorption model and the two-step adsorption model. Since the calculation results based on the two-step adsorption model showed better agreements with the experimental data, it was concluded that there is interactions between the adsorbed oxygen on the surface of liquid iron.
